A New Material and Design for Rubber Umbrella and Bell Valves with Excellent Elongation at Break

Free content from Minnesota Rubber and Plastics

Our client wanted us to create a custom rubber material for umbrella and bell valves leading to a more robust version of existing critical pump sealing components. At the same time, we would develop the material and manufacture the valves from our design facility in China, close to our client’s manufacturing operations. The client was eager to have an alternate supplier located in Southern China in addition to its current local supplier. The new compound is an ideal candidate to manufacture using highly efficient vertical injection processes. We also needed to improve the umbrella valve’s sealing performance, which would require a refined design and a new molding concept.
